Diolaze: Diolaze is an advanced laser hair removal procedure that safely and gently eliminates unwanted hair. It has one of the largest treatment spot sizes, making treatments convenient and fast. It is more comfortable than other devices on the market because the built-in skin cooling surface is one of the largest for all hair removal devices. The number of treatments varies from 5-10 sessions every 4-8 weeks. There are longer intervals for body hair (6-8 weeks) than for facial hair (4-6 weeks) in the first 3 sessions. In subsequent sessions the intervals on the face may increase to 8 weeks and on the body to 10-12 weeks, legs may require 15 week intervals.
